If you love someone enough to plan a real future with them and wanted to marry them or so you say....then you work through shit, you discuss shit and if you really love someone you work through it and knuckle down right? you don't a few days after an issue message your ex and start promising them the world and start sleeping with them....Regardless of how much your heads fallen off or your upset of the situation because if you love someone you literally couldn't go near anyone else like that...
Especially if the person (me) who made the mistake..not major not break up worthy is trying to resolve it and vowes to put whatever effort needed to find a solution and move forward....
My ex did this just went off to his ex and future faked her with lies to get sex from her. He unblocked and reblocked me multiple times in the 6 months I was pleading for us to fix us and move through it....while sleeping with her and promising her the world (I didn't know this at the time) and when he got caught out he said "I told her what she wanted to hear so I could get what I wanted from her"
Fundamentally no good person would or could do this right?
I'm so low and struggling with all this...sorry
